Application fuga January 25, 192e. semina. 4sean.

This invention has for its object the provision of a mower attachmentfor motor operated trucks or the like, and is primarily intended forcutting down weeds and grass u in ditches along a road or highway, andmore especially in places where the presence oi gravel renders the useof a grader 1mpossible for this purpose.

ln carrying out the invention I make use lll oil a mower supported on atruck and operated :trom the rear wheel thereof, said cutting mechanismbeing' capable of tilting adjustment with relation to the ground, andalso capable of being vertically and horizontally lll adjusted withrelation the. ground 1ndependently of the tlltmg ad]ustment, so that thecutting mechanism may be arranged to operate under various conditions.o.

'lhe nature and advantages of the 1nvenllll tion will be betterunderstood when the 'lollowing -detailed description is read 1nconnection with the accompanying drawings,

the invention residing in the construction, combination and arrangementof vparts as llll claimed.

In the drawings forming part of this application, lilre numerals ofreference indicate similar parts in the several views, and wherein:

ll Figure l is a side elevation of the attachment showing how it ismounted upon a motor operated truck.

Figure Q is a top plan view of the attachment mounted on the truck.

Figure 3 is a view taken at a right angle to Figure l.

Figure l is a sectional view on line 4--42 ol Figure 2.

Figure 5 is a sectional view on line 5--5 oil Fi ure l.

Rel'erring to the drawings in detail, A. indicates generally a movablecarrier, which may be oli any suitable design or construction, but lorthe purpose oi illustration the carrier herein shown is in the nature ofa motor operated truclt.

rlhc cutting mechanism per se is of ordinary well lrnown construction,and is indicated generally E. The cutting mechanism is arranged at thelower end of a beam lll which is preferably of the cross sectionalcontour shown in Figure 5, for sliding movement through a suitable guidel1. This guide is pivotally mounted as at l2 at one side oi the carrieras clearly shown in Figure l, so that the beam l together with the lilllill

cutting mechanism B can be moved vertlcally with relation to the ground,or adjusted to position the cutting mechanism B at any desired distanceaway from the carrier when adjusted horizontally, For adjusting the beaml0 and the cutting mechanism B vertically in the manner just stated, Iemploy a cable 13 which is secured to the beam l() at an appropriatepoint in its length as at 14C, this cable being trained over a drum ljournaled in a suitable bracket i6 mounted on the carrier A.. The drumis op erated by means of a hand wheel 17, so that the cable 13 can bewound about or unwound from the drum as the occasion may require, thedrum being held against retrograde movement by means of a pawl andratchet mechanism, indicated at 18. Now, for tilting the beam l() inorder to shift the cutting mechanism yB in a horizontal plane toward andaway from the carrier, and thus position the mower in proper relation tothe work, I employ a cable 19 which is secured to the upper end of thebeam as shown in Figure l, and which cable is adapted to be wound aboutand unwound from a drum 20 operated by means of a hand wheel 2l.Consequent y the cable 19 can bc operated in a convenient manner, whilethe drum is held against retro rade movement by a pawl and ratchet mecanism indicated at 22.

This drum is mounted on a suitable bracket 23 fixed to the carrier asindicated.

In addition to these adjustments, the cutting mechanism B is capable cipivotal or tilting movement on the lower end ci the beam l0, so that thecutting mechanism can be arranged at any desired angle with relation tothe ground to accomplish its purpose.. In this connection the cuttingmechanism B is provided with a segmental bracket 24@ which torms part ofa casting as clearly shown in Figure d, while the curved portion of 'thebracket is provided with teeth Q5, as clearly indicated in Figure d.Meshing with these teeth 25 is a pinion 9.6 carried by the adjacent endot a shaft mounted on suitable bearings for rotation, and projectingabove the' carrier and arranged obliquely with relation thereto. Thisshaft includes telescopic sections and one of which is provided with ahand wheel 28 through the instrumentality ci which the shaft can berotated in either direction to tilt the cutting mechanism B as theoccasion may require. This shaft is also provided with a Y source ofpower, and as shown in this specific instance is operated from one" ofthe traction wheels of a truck, for which purpose I rovide said wheelwith a sprocket 33 over w ich is trained an endless chain 34. This chainextends upwardly and is also trai-ned over the s rocket carried by astub shaft 35, the latter eing 'ournaled in a bearing indicated at 36.ne end of this shaft is equipped with a beveled gear 37 which mesheswith a similar gear 38vcarried by an operating shaft for the cuttingmechanism.

This shaft just mentioned includes telescopic section 39 and 40respectively which allows the cutting mechanism to be adjustedvertically with relation to the ground in the manner above described.The section 40 of this shaft is journaled in an inverted U-shaped memberwhich is also pivoted upon the casting above referred to and as clearlyshown in Figure 3, and is equipped with a pinion 41 which meshes with agear 42 carried by the shaft 43 which is journaled in said casting.Arranged on this gear is a disk 42 which operates a pitman 43eccentrieally connected with the disk, and also connected with thecutter bar of the cuttin mechanism to reciprocate the latter inci ent tothe rotation of the said disk. Consequently when the truck is in oeration, the cutting mechanism is operated rom the rear wheel thereof,and by reason of the construction and arrangement of parts abovedescribed, said cutting mechanism can be Very easily and convenientlyadjusted to meet the requirements and condition of the roadway toaccomplish the purpose for which it is intended. However, it is to beborne in mind that power for operating the cutting mechanism can beobtained from any other suitable source, and the means herein shown forthat purpose is merely illustrative of one embodiment of the invention.

While it is believed that from the foregoing description the nature andadvantages of the invention will be readily apparent, I desire to haveit understood that I do not limit myself to what is herein shown anddescribed, and that such changes may be resorted to when desired as fallwithin the scope of what is claimed.

'What I claim is The combination with a support, of a guide mountedthereon and spaced therefrom, a beam slidable on the guide, means foradjusting the beam through the guide, a cutting mechanism pivotallymounted on the lower end of the beam and including a bracket having atoothed segmental portion, a shaft lournaled on the support and arrangedo liquely thereto, a gear carried by the shaft and meshing with theteeth of said segment, whereby said cutting mechanism can be adjustedpivotally with relation to said beam, and means for rotating said shaft.

In testimony whereof I affix my signature.
